Evidence of an extraterrestrial origin for some organic constituents of meteorites


Play all audios:

ABSTRACT THE presence of organic matter within samples of carbonaceous chondrites is now well established1–5. However, it has been suggested from several sources that considerable


terrestrial contamination of these meteorites may have occurred and that the organic matter is not indigenous. The experiments reported in this communication were conducted to determine


whether the isotopic composition of the meteorite organic matter afforded any evidence regarding the origin of the compounds. Access through your institution Buy or subscribe This is a
